CABLE RAILWAY.

SPECIFICATION forming part of Letters Patent No. 315,983, dated Aprilll,1885.

Application filed February 3, 1385. (No model.)

To @ZZ whom it may concern.-

Be it known that I, WILLIAM WHAnroN, .I r., a citizen ofthe UnitedStates, and a resident of Philadelphia, Pennsylvania, have inventedcertain Improvements in Cable Railways, of which the following is aspecification.- My invention relates to doubletrack cable roads; and itconsists in connecting the conduits to the sills of the tracks byadjustable 10 stay rods, substantially in the manner described andclaimed, and for the purpose explained hereinafter.

In the accompanying drawings, Figure lis a sectional perspective view ofpart of a doubletrack street-railway, with a cable-conduit for eachtrack, no pavement being shown in this view, as it would interfere withthe proper exhibition of thelongitudinal sills and transverse stay-rods;Fig. 2, a plan view of Fig. 1; Fig. 8, a transverse section, drawn to anenlarged scale, on the line 1 2, Fig. 2; and Fig. 4, a View illustratinga modification of my invention.

A and A are the longitudinal sills of one track and B and B the sills ofthe adjoining track of a double-track cable road, the usual rails, a,being secured to these sills. There are two cable-conduits, D D', onebeing situated midway between the sills of each track, and each conduitis connected to the sills ofthetrack to which it appertains by asuccession of adj ustable stay-rods, G G. Thus one side of the conduit Dis connected to the sill A by the adjustable stay-rods G, arranged atsuitable intervals, and the opposite side of the conduit 5 is connectedby similar rods, G', to the sill A,

a similar system of adjustable transverse stayrods being combined withthe sills and conduit of the other track. 'Ihe inner sill A of one trackis connected to the inner sill B of the other track by a succession ofadjustable stayrods, II,which are preferably arranged in respect to thestay-rods G G in the manner shown in the plan view, Fig. 2. ThesestayrodsHconstitute theimportant element of the combination forming thesubject of my invention.

It will be necessary to refer here to the Letters Patent No. 281,593,granted to me July 17, 1883, in which a cable-conduit is connected 5o byadjustable stay-rods to the sills of a single track, so that in layingthe conduit it can le easily and permanently adjusted in its properposition, and the parallelism of the slot of the conduit with the railsquickly attained and positively preserved.

Practical experience in the construction and operation of cable roads ofthe class to which my invention relates has shown that it is more important to maintain a proper opening of the slot of the conduit than tomaintain the par- 6o allelism of this slot with the rails of the track,for the gripping devices of the cars are permitted to have such lateralplay that they readily accommodate themselves to the slot when thelatter is out of truth with the rails. Per- 6 5 manent or non-adjustable connections between the sills and conduit have proved to beimpracticable, owing to the influence of changes of temperature, manyinstances having occurred in which there has been such contrac- 7o tionof the slot, owing to the expansion of the soil during a frost, as toprevent the free traversing therein of the gripping devices. By makingthe transverse tie-rods adjustable, as in my aforesaid patent, thisdiftculty can be obviated to a certain degree.

The conduits often used for cable roads are those for which LettersPatent No. 287, 220 were granted to A. Bonzano, October 23, 1883, andthe adjustable tie-rods described in my said patent 8o are especiallyapplicable to these conduits, for, as the latter are made of sheetiron,the sides are apt to yield during a frost, the slot consequentlybecoming contracted. The object of my present invention is to renderthese 8 5 adjustable tie-rods more available in connection with doubletracks, for insuring a proper width of slot in both conduits.

The maintenance of the outer side of the conduit D of one track in itsproper position is 9o dependent upon the sill A and tie-rods G, theouter side of the conduit D being held in place by the sill B andsimilar tie-rods; but, owing to the intermediate tie-rods H, greaterstability is imparted to the sills A and B, and they are in the bestcondition for permitting the rods G to be used for increasing the widthof the slots of both conduits when such increase is demanded.

Instead of intermediate rods, H, the rods G roo may extend from conduitto conduit, as shown `to the roadway in the manner described in anapplication iiled by myself and Edward Samuel, bearing even dateherewith, and des ignated as application D.77

I claim as my invention- The combination of the two cable-conduit of adouble-track cable road and the sills of the tracks with adjustablestay-rods, whereby zo the inner sills of the two tracks are connectedtogether and to the inner sides of the two conduits, substantially asset forth.

In testimony whereof Ihave signed my name to this specification in thepresence of two sub- 2 5 scribing witnesses.
